Who am I anymore?

I am feeling very disconnected from my inner self.  Sometimes I wonder if the real me still exists.  I feel like my husband has slowly and deliberately killed my spirit and I question who I am anymore.  He treats me like I'm incapable of completing any task without is direction.  Nothing I do is right!!  He is always giving me orders, telling me how stupid I am,  and criticizing everything I say or do.  He makes it difficult for me to have any friends or get involved in any outside activities.  I feel isolated and alone.  I have made the decision to leave by August.  At times I feel good about my decision and other times I feel anxiety and question whether I will have the strength to do it.
